Decomposing with Playing Cards
In partners students circle the groups they see on the large playing cards. Each large playing card is placed in a plastic sleeve so students can use dry-erase markers to circle the groups. On the activity "Playing Card" the student writes the number of the card they took in the box and writes four ways that they see the number. (e.g., 4 is the card selected. In one box they might write 2 and 2, in another 3 and 1, and another 4 and 0)
